I'm finding this quite facinating. I am hovering on a breakthrough in 100 at the 20. My game has shown significant improvement lately. For the last three days I have hit my all time high 4 times. That score would be 153. Now here is where it gets interesting and why I am bringing this up. Last night as I was tossing 100 at the 20, I hit a few one marks and I actually hit a zero mark at the end of my third leg of 10. I was having a great game and thought I was sure to beat my all time high. After the game I added up all my scores and there it was looking back at me again 153. Now, I have not hit a 152 or a 151. I did not hit anything above a 153. I did hit a 150, but only one. My next highest scores are 144, 148, and such. So how does the brain know to stop exactly at 153? I swear as I look over my scores this is impossible. There are 3 one marks. 6 two marks. A load of three marks. One mark more in any of these positions and I would have beaten my best. (Just One) How does the brain Know? It's like being in the Twilight Zone.
